Abstract

The invention relates to a double-sided shadow elimination touch screen sensor and a production process thereof. The double-sided shadow elimination touch screen sensor comprises an ultrathin glass substrate, shadow elimination layers, a top ITO sensing layer, a bottom ITO sensing layer and a glass cover plate, the upper surface and the lower surface of the ultrathin glass substrate are plated with the shadow elimination layers, the top ITO sensing layer is plated on the surface of the shadow elimination layer on the upper portion of the ultrathin glass substrate, the bottom ITO sensing layer is plated on the surface of the shadow elimination layer on the lower portion of the ultrathin glass substrate, and the ultrathin glass substrate is attached with the glass cover plate through an OCA. According to the double-sided shadow elimination touch screen sensor and the production process thereof, the structure of the touch screen sensor is optimized, visible light transmission is increased, and the process cost is reduced.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a double-sided shadow erasing touch screen sensor and a production process thereof. Background technique [0002] Capacitive touch screens work by using the current induction of the human body. The capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are coated with a layer of ITO, and the outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating is used as the working surface. Four electrodes, the inner ITO is the shielding layer to ensure a good working environment. When a finger touches the metal layer, due to the electric field of the human body, a coupling capacitance is formed between the user and the surface of the touch screen. For high-frequency currents, the capacitance is a direct conductor, so the finger absorbs a small current from the contact point. This current flow...
